gomez, i want to thank ben stein, apologies to matt damon, we ran out of time. thank you for joining us, "nightline" is next. ,, >>> tonight on "nightline." dream fulfilled? today as the president addresses the nation from the steps of the lincoln memorial. and two women who were here 50 years ago to share martin luther king jr.'s dream. >>> it is what is painting the town red and purple and every color of the rainbow. it is the color run, and revolutionizing the way we run and stay fit. >>> and there is something for everyone in our reunion round-up. from insync to the vma's to a father and son, we guarantee you from new york city, this is "nightline" with cynthia mcfadden. >>> good evening, when martin luther king jr. stood up to address the nation on the steps of the lincoln memorial, his words did not use the phrase "i have a dream." he had used those words before, but they wanted something different. and then, mahalia jackson said "tell them about the dream." and he said the words that still resonate today. two young african american girls went to the gathering, and had a message.
